74HC258N datasheet

 

Description :

The 74HC258 / 74HC258N / 74HCT258 are high-speed Si-gate CMOS devices and are pin compatible with Low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.

The 74HC258 / 74HCT258 have four identical 2-input multiplexers with 3-state outputs, which select 4 bits of data from two sources and are controlled by a common data select input (S).

Pinouts :

Features :

1. Inverting data path

2. 3-state outputs interface directly with system bus

3. Output capability: bus driver

4. ICC category: MSI

PCA9544APW datasheet

 

Description :

The PCA9544A, PCA9544APW is a 1-of-4 bidirectional translating multiplexer, controlled via the I2C-bus. The SCL/SDA upstream pair fans out to fourSCx/SDx downstream pairs, or channels.

The pass gates of the multiplexer are constructed such that the VDDpin can be used to limit the maximum high voltage which is passedby the PCA9544A. This allows the use of different bus voltages on each SCx/SDx pair, so that 1.8 V, 2.5 V or 3.3 V parts can communicate with 5 V parts without any additional protection. External pull-up resistors pull the bus up to the desired voltage level for each channel. All I/O pins are 5 V tolerant.

 

Block Diagram :

Features :

1. 1-of-4 bidirectional translating multiplexer

2. I2C-bus interface logic; compatible with SMBus

3. 4 active LOW interrupt inputs

4. Active LOW interrupt output

5. 3 address pins allowing up to 8 devices on the I2C-bus

6. Channel selection via I2C-bus

7. Power-up with all multiplexer channels deselected
